<pre>Currently, size is set to 65535 if the set is dynamic AND it is used by the
ruleset.
I have a kernel patch here that I plan to test and then submit:
diff --git a/net/netfilter/nf_tables_api.c b/net/netfilter/nf_tables_api.c
index 29c651804cb2..49c068d9b209 100644
--- a/net/netfilter/nf_tables_api.c
+++ b/net/netfilter/nf_tables_api.c
@@ -4998,6 +4998,9 @@ static int nf_tables_newset(struct sk_buff *skb, const
struct nfnl_info *info,
return -EINVAL;
}
+ if (flags & NFT_SET_EVAL && !desc.size)
+ desc.size = 0xffff;

if (nla[NFTA_SET_EXPR] || nla[NFTA_SET_EXPRESSIONS])
desc.expr = true;
This sets on the cap earlier, by the time the dynamic set is created.</pre>
